USDC 稳定币扩展到 zkSync，现已支持 16 个区块链

Stablecoin issuer Circle has expanded support for its native stablecoin, USD Coin (USDC), to Ethereum zero-knowledge layer-2 solution zkSync.

稳定币发行商 Circle 已将其原生稳定币 USD Coin (USDC) 的支持扩展到以太坊零知识第 2 层解决方案 zkSync。

“Many leading ecosystem apps and DeFi protocols are expected to support native USDC on zkSync for payments, trading, borrowing, lending,” wrote Circle in its April 9 announcement; developers can use USDC on zkSync to build on a stable foundation that’s built to last and officially supported by Circle. With the addition of zkSync, USDC is now supported on 16 blockchains, including Ethereum, Solana, Base, Arbitrum, and others. 

Circle 在 4 月 9 日的公告中写道：“许多领先的生态系统应用程序和 DeFi 协议预计将支持 zkSync 上的原生 USDC 进行支付、交易、借贷”。开发人员可以在 zkSync 上使用 USDC 构建持久稳定的基础，并得到 Circle 的官方支持。随着 zkSync 的加入，USDC 现在支持 16 个区块链，包括以太坊、Solana、Base、Arbitrum 等。

Zero-knowledge proofs determine the integrity of a transaction without disclosing the supporting evidence. Meanwhile, rollups bundle transactions off the Ethereum main layer and club them into a single transaction. Together, they form the core of the zkSync technology, which processes transactions at record speed and low cost at layer 2 and sends the finalized proof back to the Ethereum mainnet. As of April 9, 2024, the zkSync ecosystem includes over 180 decentralized applications and over 5.7 million unique active wallet addresses over the last 30 days.

零知识证明无需披露支持证据即可确定交易的完整性。与此同时，汇总将以太坊主层的交易捆绑在一起，并将它们组合成一个交易。它们共同构成了 zkSync 技术的核心，该技术在第 2 层以创纪录的速度和低成本处理交易，并将最终的证明发送回以太坊主网。截至 2024 年 4 月 9 日，zkSync 生态系统包括过去 30 天内超过 180 个去中心化应用程序和超过 570 万个独特的活跃钱包地址。

Like USDC on other blockchains, the zkSync USDC can be redeemed one-for-one for U.S. dollars directly via Circle or via digital wallets and exchanges. The zkSync USDC can also be swapped for other USDCs via cross-chain bridges. Institution investors can also access the stablecoin via Circle Mint. “Businesses and developers use zkSync to benefit from fast, low cost transactions and native account abstraction,” Circle wrote, adding that “zkSync is on a mission to increase Ethereum’s throughput, and to fully preserve its foundational values.”

与其他区块链上的 USDC 一样，zkSync USDC 可以直接通过 Circle 或通过数字钱包和交易所一对一兑换美元。 zkSync USDC 还可以通过跨链桥交换为其他 USDC。机构投资者还可以通过 Circle Mint 获取稳定币。 Circle 写道：“企业和开发人员使用 zkSync 来受益于快速、低成本的交易和本机帐户抽象。”他补充道，“zkSync 的使命是提高以太坊的吞吐量，并充分保留其基本价值。”

Circle has been mostly expanding access to USDC to other blockchains, although it has halted such efforts from time to time. On Feb. 21, Circle abruptly ceased USDC minting on the Tron blockchain. Circle did not give a reason for ending Tron support, only saying it “continually assesses the suitability of all blockchains” as part of its risk management process. 

Circle 一直在将 USDC 的访问范围扩大到其他区块链，尽管它不时停止此类努力。 2 月 21 日，Circle 突然停止在 Tron 区块链上铸造 USDC。 Circle 没有给出终止 Tron 支持的原因，只是表示它“不断评估所有区块链的适用性”，作为其风险管理流程的一部分。

Last year, the U.S. Securities and Exchange Commission sued Justin Sun and the Tron Foundation alleging they offered unregistered securities and conducted manipulative trading, which Sun denies.

去年，美国证券交易委员会起诉孙宇晨和波场基金会，指控他们提供未经注册的证券并进行操纵交易，孙宇晨对此予以否认。
